Bluetooth mouses have the advantage that you can easily connect to your laptop or desktop. You're not tied to the length of a cable. Another advantage of a Bluetooth mouse is that you can easily set the speed of the mouse. In addition, you can easily take a Bluetooth mouse with you and work with it on the train, for example, when you're on the road. This way, you don't stuck behind a cable and no cord can get tangled when you carry the mouse in a bag.
